Insertion of a genomic Cirl fragment at the attP site in CirlKO.attP.w-; the fragment contains a triple CD4 immunoglobulin repeat spacer cassette (marked with poly-Tag:V5 tags) that results in elongation (approximately 20nm) of the extracellular domain; also contains a w+* marker.
The responses of Cirl3xCD4 mutant lch5 neurons in larvae to mechanical stimulation are reduced, compared to controls.
